If 30% of the girls who attended seminar on topic B are married, then find the number of girls who are unmarried from the same seminar topic.
Total number of students attended seminar on topic B = (40/100) × 500 = 200 Total number of students attended seminar on topic C = (20/100) × 500 = 100 Number of boys attended seminar on topic B = (3/5) × 200 = 120 Number of girls attended seminar on topic B = (2/5) × 200 = 80 Number of boys attended seminar on topic A = 120 - 100 = 20 Number of boys attended seminar on topic C = (1/4) × 100 = 25 Number of girls attended seminar on topic C = (3/4) × 100 = 75 Number of boys attended seminar on topic D = 150 - 90 = 60 Total number of students attended seminar on topic A = 500 – (200 + 100 + 150) = 50 Number of girls attended seminar on topic A = 50 - 20 = 30 Number of unmarried girls who attended seminar on topic B = (70/100) × 80 = 56
96% of 4500 – 34% of 650 = ?
5555 ÷ 11 ÷ 5 = 100 + ?
154 × 7 + 480 × 5 = ?% of 6956
35% of 840 + 162 = ? – 25% × 300
Simplify: (23×32) ÷6
?3 - 25 × 11 = 30 - 15 × 12
(3333 ÷30) + (785 ÷25) + (2981 ÷11) = ?
5.45% of 1854 – 37.5% of 1096 = ? – 48% of 630
26 2 – 13% of 400 + (529 ÷ 23 2 ) = ? 2
